AI for Data Center Development.
Develop the world's most critical projects on full information.
Infrastructure that keeps developers ahead.
About Sandbox
Data center development is a dense network of interdependent decisions – power, land, fiber, regulatory,
cooling – each one reshaping every other as conditions change. Today these decisions are made against
fragmented data across spreadsheets, inboxes, and siloed tools. Sandbox is the infrastructure
that captures
this dependency structure and runs workflows, AI agents, and deliverables on top of it.
Infrastructure, not Application
Point solutions sit on top of fragmented data and inherit its limits. Sandbox is the layer
beneath them, where
every analytical tool, AI agent, and human judgement a firm uses becomes usable,
comparable, and additive.
A Graph at the Core
Development is a system of interdependent decisions. Only a graph and a purpose-built
ontology can model
them as such. Entities vary across jurisdictions and asset types; First principle
relations between them do not.
From Dust to Data Center
Sandbox v1 targets feasibility and underwriting. Subsequent phases extend the same graph
across the full
project lifecycle, closing the gap between plan and execution.
Built for critical Projects
Development is uncertain, judgement-heavy, decision-dense, multi-stakeholder, and
lifecycle-spanning.
Generic project management software is not designed for that work. Sandbox is.
Data Room
Build on everything your firm already knows (and beyond).
Sandbox is the data layer that captures, in structure, the way a development project actually works.
Every entity, dependency, and decision is part of one connected system. Owned by the firm, accessible
to everyone working on it. Sandbox is the super-brain of your firm.
Data Ingestion
Project data
Documents, designs, models, and filings generated for a project
Regulatory & Permitting
Codes, zoning, approvals, planning records, etc.
Power & Infrastructure
Grid, utility, fiber, water, equipment data, etc.
Market & Capital
Costs, rates, benchmarks, transactions, financing conditions, etc.
Stakeholders & Communication
Counterparties, contacts, and the firm's working exchanges
Firm Knowledge
The firm's accumulated outcomes, history, and judgment
Knowledge as a Firms Competitive Advantage
Institutional experience currently held by individuals and distributed across fragmented
systems becomes
structured, queryable, firm-owned intelligence. Every professional works against firm's
full history & context.
Provenance on Everything
Every data point carries origin, confidence, and version. Every output Sandbox produces,
and every input it
draws from, traces back to the exact data point in the data room.
Collaboration
No project is built alone. Sandbox enables easy-to-use permissioned spaces, scoped
external access, and
shareable links that let everyone from LPs to regulatory counsel contribute.
Forward-deployed
Sandbox is set up by a dedicated forward-deployed team that connects existing systems,
ingests historic
project archives, and tailors the ontology to the firm's demands & workflows.
Agent Output
Sandbox brings the full power of large language models to development. Every model, every
workflow, every
agent answer is grounded in the full state of the project, captured in the Sandbox graph. Workflows collapse
weeks of work into minutes, thousands of scenarios are evaluated where a team today evaluates three, and
connections, risks, and dependencies a team would otherwise miss are surfaced automatically.
The focus moves from analyst capacity to judgement itself.
Assistant
A LLM reasoning layer grounded in the firm's entire source of truth. Analysis is
faster,
sharper, and traceable to every underlying node.
Workflows
Composable workflows tailored to how a firm already works. Deployed in days,
not
months, and built up as the work evolves.
Live Activities
Continuous monitoring across every input to the project. Alerts on
cascades,
pattern recognition, regulatory shifts, market moves, and material deviations.
Interoperability
Bringing reasoning to where the work already happens. Sandbox connects to
existing
business apps, preserving and enriching them with full project context.
Building Critical Infrastructure for Critical Infrstructure
A platform that holds a firm's full project state, stakeholder network, and decision history concentrates risk that no single tool in a firm has ever concentrated before. That concentration is what makes Sandbox valuable – and what makes its security architecture the single most important thing we build. Every part of Sandbox is designed around that responsibility.
Your data stays yours
Every firm operates in its own dedicated environment. No shared storage, no shared model training, no access between firms under any condition.
Permissions at the document and data level
Access can be set precisely by data and document. An LP granted access to an investment memo cannot reach anything else not explicitly shared.
Full audit trail, built in
The graph-based architecture allows every data point & output to carry a complete record of where it came from, who accessed it, and how it changed.
Partner-audited architecture
Held to the standard of the firms deploying it. Sandbox is being co-developed alongside institutional partners with the highest security standards in the industry.
Certifications & Compliance
SOC 2 Type II
ISO 27001
ISO 27017
GDPR Compliant
// Targets we build to. EU-based infrastructure and on-premise deployment available by
default.
Compliance is treated as an outcome of correct design rather than later audit overlay.
Case studies and research
Sandbox is being co-developed with a selected group of institutional developers across
Europe.
Early deployments, foundational research, and technical publications are collected here.
